Abstract: For increasing the retention of solid fission products in coated fuel particles, investigations are made on oxide fuel kernels containing special refractory oxides, e.g. Al$_{2}$O$_{3}$. It is the aim of this work to test the possibility of retaining solid fission products in the kernel by formation of stable ternary oxides. Using the Hydrolysis Process, U0$_{2}$ and (U,Th) O$_{2}$ kernels are prepared which contain the solid fission products Sr, Ba, Ce in concentrations corresponding to a burnup of about 10 % fima. After an out-of-pile heat treatment of these kernels of the fission product release is measured. The Sr release at 1250 °C is found tobe smaller by a factor 20 to 100 if the kernels contain Al$_{2}$O$_{3}$ in amounts of 1 to 5 weight percent. The solid fission products are enriched in the inclusions of Al$_{2}$O$_{3}$ which is not soluble in the UO$_{2}$ matrix of the kernel.
